@necrevistonnezr Thanks for the tip. I updated to 3.2.3 (previously was at 3.2.1) and now the web interface is working in Firefox. (Not working in Safari, for some reason.) Still no luck with the iOS app, though.

@necrevistonnezr I'm getting a blank screen in the iOS app, too. But now even the web version on desktop is failing to load. Latest updates on Nextcloud/Collabora/Cloudron and I have the Collabora app using a wildcard for my domain, and the Nextcloud Collabora app is configured and updated. Not sure what is going on, it has worked in the past.

I have this question to. What to do when some of these Nextcloud apps require something to execute on the server itself. This is my main example, but also for a preview generator that needs something added to a cron job, etc.
